BentoML is a Python library for building online serving systems optimized for AI apps and model inference. Prior to 1.4.37, the field in accepts arbitrary strings that are interpolated directly into Dockerfile commands without sanitization. Since is semantically a list of OS package names (data), users do not expect values to be interpreted as shell commands. A malicious achieves arbitrary command execution during / . Version 1.4.37 fixes the issue.
